INCANDESCENT GAS-LAMP.

Specification of Letters Patent.

Patented Dec. 24:, 1907.

-T 0 all whom it may concern:

Be it known that I, ALCORN REoToR, of New York city, county and State of New York, have invented a new and Improved Incandescent Gas-Lamp, of which the following is a full, clear, and exact description.

My invention relates to improvements in incandescent gas lamps, and the object of my invention is to produce a gas lamp of very high candle power, and of very high efliciency. In attaining this object I utilize to a certain extent the principle of the Argand burner, except that I use no wick, but I have found that by preparing a large center draft for the burner and arranging the structure so that a large air supply will be delivered both inside and outside the mantle, I can envelop the latter in a flame on both sides, which will heat it to very high incandescence, and will cause it therefore to give an exceedingly brilliant light. I have found further that I can induce a draft during the consumption of gas which will cause such a strong current of air to flow through the cen ter tube or draft tube that the inflow will run a small wind wheel which in turn is capable of operating a blower, and the latter can be made to supply a forced draft for thelamp, thus causing a still higher state of incandescence at the mantle.

With these ends in view my invention consists of an improved incandescent gas lamp, the construction and operation of which will be hereinafter described, and the novel features claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which similar letters and figures of reference indicate corresponding parts in all the views.

Figure 1 is a central vertical section of a lamp showing my improvements. Fig. 2 is a broken outside elevation of the same. Fig. 3 is a broken side elevation of a slightly modified form of the lamp. Fig. 4 is asectional plan of the burner and connected parts. F ig. 5, is a detail sectional view showing a slightly modified form of invention. Fig. 6 is a detail sectional view showing another slight modification of the burner. Fig. 7 is a central vertical section with parts in elevation showing the lamp with the air forcing attachment. Fig. 8 is a sectional plan on the line 88 of Fig. 7, and Fig. 9 is a side elevation partly in section of a part of the structure shown in Fig. 7.

The lamp is provided with any suitable bunsen 10 having a nipple 11 for connecting with a gas fixture and air openings 12 as usual. A connection 13 which fits the bunsen tube carries the air and gas supply ipes 14 which diverge from the bunsen and de 'ver into the inwardly projecting extensions 15 which form a part of the burner 16 and the latter may be, except for the details of the air draft, of any suitable design, and it can be of one piece, with the tubes 14, or separate. as preferred. The air and gas tubes 14 and 15 deliver into'and merge into the annular passage 17 which is formed between the wall of the central draft tube 18 and the wall 19 which forms the upper extension of the outer wall of the flues 15 and the air and gas passing up through the draft tube and through the tubes or flues 15 are thus carried forcibly up into and through the mantle 20. Themantle 20 can be of any approved construction, but I prefer to have it open at the to although my invention has nothing to o with the mantle.

The mantle can be supported in any convenient way, but to show a means of support I have provided a rod 21 which is carried in a holder 22 on the post 23, and this is seated, as shown at 24 (Fig. 1) on top of the bunsen 10. The burner has the customary outer shell 25 in which are the air inlet ports 26 and a chimney support 27 is provided, the walls of which serve to direct the incoming air upward against the mantle, and the chimney support has the ordinary chimney clips 28 which press against and secure the chimney 29.

It'will be seen that the air and gas passing up through the bunsen 10 will be thoroughly mingled and will pass on through the flues 14 and extensions 15 thereof and be delivered through the circular vent 17 so as to impinge on all parts of the mantle and combustion will be further promoted by air rushing up through the center tube or draft tube 18 and through the ports 26. If desired, the passage of fuel through the flues can be checked a little, as, for instance, by placing a bent wire 30 (see Fig. 5) in the annular vent the center or draft tube 18 can also be checked and made to impinge in numerous jets upon the mantle by using an improved extension 18 of the draft tube which extension is provided with numerous perforations, or a wire gauze extension can be used.

In Figs. 7 to 9 I have shown the lamp provided with an air forcing apparatus operated by the draft through the draft tube or center tube and means for supplying the forced air and gas efifectively to the mantle. As illustrated, the center or draft tube 18 is projected downward so asto form an extension or casing 31 and this is preferably larger in diameter than the draft tube, is open at the bottom, and is supported on the pipes or tubes 14 which are elongated to provide for the air forcing apparatus. The casing 31 carries a wind wheel 32 which can be of any suitable construction, and this is secured to a shaft 33 which likewise can be mounted in any convenient manner, and which as shown is mounted at the top in a cross bar 34 extending across the top of the casing 31 and at the bottom in a bearing 35 on the top of the bunsen tube 10. The shaft 33 which is driven with the wheel 32 carries the fans 36 of a blower comprising the said fans and a casing 37, but the blower can be of any approved construction, as I do not claim the blower in detail. As shown the blower casing is open at top and bottom, and the air is drawn in through these openings and forced out through the tube 38, as described below. The blower casing 37 has an outlet pipe 38 which delivers into the lower end of the bunsen tube 10 below the openings 12 and so when the lamp is lighted and the draft induced the wind wheel 32 will drive the blower and force an excess air supply into the bunsen tube. Iwish it clearly understood that any wind operated motor can be substituted for the wind wheel, and that any approved form of blower can be used. The casing 31 above referred to, is open at the bottom and delivers through pipes or tubes 39 into the lamp at a point between the wall 27 and the wall 19 so that a portion of the air passing from the casing will go through the said tubes 39 and be delivered to the outer side of the mantle, and in order that this action may be certain, the draft tube 18 is as above stated, smaller than the casing 31, though the draft tube and casing form essentially one structure. In this form of the apparatus, where the forced air draft is used, the tubes or pipes 14 are elongated as stated, and they deliver into an annular chamber 15 at the bottom of the burner and the air and gas pass from this chamber up through the annular passage 17, as already stated, except that the quantity passing is increased. I have found by actual experiment that the quantity of air passing through the draft tube is sufficient to drive the wind motor or wheel 32 at a very high rate of speed, so that it will operate the blower, but if desired, any suitable gearing can be arranged between the wind wheel and blower without affecting the principle of my invention, although, as stated, the right rate of speed of the wind wheel renders the use of gearing superfluous in most cases.-

I have shown a burner provided with two tubes 14, or with three tubes, as in Fig. 3, but it will be understood that any number of these tubes can be used, or that a single annular passage might be used for connecting the bunsen with the passage way 17 without affecting the principle of my invention.

From the foregoing description it will be seen that I have produced a lamp which has an unusual air supply, and for this reason it has excellent combustion and high efficiency, and while the form of burner is particularly adapted for lighting purposes, the mantle can be dispensed with and the structure practically as shown used as a heater with excellent results.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent,-
